The Lian Li PC-7HX is no exception when it comes to the design philosophy that Lian Li uses. The PC-7HX is constructed out of aluminum and has a solid build. Lian Li designed the PC-7HX to utilize a positive pressure cooling design with two 140mm fans in the front bezel and a single 120mm fan in the rear to exhaust the hot air. A hard drive cage is included that will support four 3.5 inch drives along with a single 2.5 inch drive. The drive cage is removable and also can be upgraded with a back-plate to provide hot swap capabilities. The front I/O panel features two USB 3.0 ports, as well as audio jacks with a cover, to hide them when they are not in use.
